Waste removal is a major challenge in all food processing environments however it is seldom more of an issue than in the fresh-cut fruit and vegetable industry. This labor-intensive process relies upon dozens of workers in each facility hand peeling and trimming fruits and vegetables prior to packaging. Food waste including peels, rinds, tops, tails, cores, and whole rejected cull pieces are generated throughout the plant, at virtually every station.
In the past, plant managers relied upon water trough flume systems running below the trim lines or perhaps belted conveyors criss-crossing the facility to collect the waste discharge and (hopefully) take it back to a collection area. Flume-carried waste needs to be dewatered prior to collection in a trailer for disposal, an expensive proposition which leaves behind hundreds of gallons of contaminated water to be treated and discharged. Belted conveyor waste can be collected in strategically placed bins which then need to be carried by lift truck and dumped in the back of the building. This is a labor-intensive proposition in itself in addition to the floor space requirements and potential safety concerns.
The REYCO Positive Pneumatic conveying system provides a simple, cost-effective solution to these problems. The system consists of a blower package which effectively pressurizes a PVC (or other) waste pipe which is strategically run beneath the cutting deck, installed in the foundation, or along the roof of the building. The pipeline is fed through one or more rotary airlocks which meter the waste into the system. Within seconds the waste is transported to a receiver or flexible hose situated above a waste truck or bin for removal. REYCO Systems® are designed to perform without the water, without the conveyors, without the lift trucks and without the associated headaches. REYCO also manufactures a complete line of related components to ensure trouble free waste handling and disposal.
The REYCO Size Reducer is designed to minimize the size of waste products before they are introduced to the REYCO Positive Pneumatic waste system. Large waste items can have a detrimental effect on any pneumatic system in two areas. The most obvious is when a piece is introduced to the system that is too large for any point in the pipe, the system has the potential to plug and must be cleared in order to continue functioning. The less obvious problem occurs when larger items are introduced to the rotary valves and overfill the pocket size. When this happens, the valve will actually shear the item as the vane rotates through the valve body. This will force the waste piece through the system however it will cause additional wear on the rotary valve itself, resulting in premature failure.
To eliminate these potential problems, REYCO designed the heavy-duty Size Reducer. This unit consists of a series of ½” thick blades which rotate through a stationary shear grid within a stainless steel housing. These units have proven effective at destroying whole heads of lettuce and cabbage as well as melon rinds and pineapple cores. The REYCO Size Reducer is engineered to mount directly above a REYCO Rotary Valve assembly in what is known as a “stack-up” system.
The REYCO Bin Leveler is designed to distribute and level waste containers resulting in a consistent fill without spillage. The system consists of a length of auger surrounded by a stainless steel shroud which is mounted immediately below the discharge receiver of a positive pneumatic waste system. Each Bin Leveler is designed to be suspended over a waste bin or trailer and is manufactured to a specific length for a given application. In most cases, the customer or installation contractor supplies the mountings and support structure for the Bin Leveler.
REYCO Sound Enclosure
REYCO designs and builds Sound Enclosures to custom-fit blower packages or other sources of sound emission to reduce facility noise levels. Excess plant noise is a continuing cause of concern where workers are present so isolation and reduction of high noise items is a critical step in maintaining a safe work environment. The Sound Enclosure is manufactured of stainless steel or painted mild steel and is insulated to reduce noise levels by as much as 30 decibels. These systems are made with bolted or lockable access doors or panels to allow for ease of service and cleaning when required.
